To all whom t may concern: i

Be it known that I, MAXTMILTAN J. O'r'io,

a citizen of the United States, residing in the borough of Manhattan,city, county, and State of New York, have invented new and usefulImprovements in Gas-J et Heaters, of which the following is adescription.

This invention has reference to heating apparatus and, particularly,relates to devices or apparatus applicable to fixtures, brackets, orarms for supplying gas light, or applicable to gas burners of any type.

Among the objects of my invention may be noted the following: to providea gas jet heater with nie-ans by which the temperature of thesurrounding atmosphere', in a room for example, may be raised through amedium applied to the ordinary fixture for gas lighting purposes; toprovide a heating apparatus which may be applied to gas burners,iixtures, etc., of any kind or description, either in combination withthe lighting means or to the exclusion thereof, for the purpose offurnishing heat to the surrounding atmosphere; to provide a simple,light, inexpensive heating device applicable to gas jet fixtures for thepurpose of providing a suiiicieiit degree ofwarmth or heat in roomswhere there is no heating apparatus or where the heating apparatus isinadequate for the purpose; to provide simple, economical, strong anddurable means for heating rooms by gas and foi-applying the same to theordinary gas fixtures or brackets, or to a specially constructed supportor bracket which is portable and maybe set upon a table or similarsupport or upon the floor or otherwise.

With the foregoing objects in view and others which will be detailedduring the course of this description, my invention consists in theparts, features, elements and combinations thereof hereinafter describedand claimed.

In order that `my invention may be clearly understood, I have provideddrawings wherein: y

Figure 1 is a View in elevation showing heating apparatus adapted to beappliedto any gas fixture or other support" `similar thereto ;V -v Fig.2 is a vertical section on line 2:-2, Fig.l 1 of the apparatus;

Fig. l is a view in elevation showing my h eating apparatus applied tothe ordinary single arm lighting fixture; I

Fig. 5 is a top plan view showing my apparatus applied to a bracket orfixture in combination with lighting means; and

Fig. 6 is a view in elevation showing the saine combination of means asin F ig. 5 applied to a portable support. adapted to be -connected to agas source.

Referring to the drawings, the numeral l indicates the cylindrical bodyof my apparatus, the same being open at its opposite ends, and providednear its lower end withv a large aperture 2 through which the gas at theburner 3 may be lighted. The burner 3 is conventional in form and may beof any known desired or preferable make.` Spe cifically, it` forms nopartof my invention. The cylindrical body l, near its lower end, is alsoprovided with a plurality of apertures 4C .encircling the bodyandadapted to supply a suflicient amount of air for combustion purposes,in combination with the apertures 5 in the conical supporting shell 6rigidly secured in any suitable manner at 7 to the tubular stem 8 of theburner 3, the

y said stem 8 having an aperture 9 which also furnished air to aid incombustion of the gas. The conical shell 6 is, at itsupper open end,provided with an inturned, substantially U-shaped flange i0, whichreceives within its opening the outturned flange 11 of a ring member l2removably secured within the base of the cylinder below the encirclingrow of apertures 4. l Thus the cylindrical body is supported removablyupon the ring 12, which ring in turn is supported by the shell 6, andthe latter in turn supported by the stem 8 of the burner, said stemextending below the shell 6 a suicient distance to provide a fixture forapplication to the usual vburner-valve 13 carried by the usual bracketor arm 14C fixed to the usual source of supply. The shell 6 is alsosecured to, and braced by, the stem V8 of the burner by means of adiaphragm l5, through the center of which the i stein 8 passes,andwhich'diaphragm, at its This aiiords a very iirm support for theheating apparatus as a whole, which latter as before noted, is removablysecured to the said support, the engagement between the ring v12 and thecylinder 1 being trictional, tight and steady. By making` the cylinderand itssupportedparts removable, as noted the drum supported in thecylinder can be removed when necessary for repairs or replacement.

The drum `mounted within is shown as composed,-Figs. two end members ordisks 19 provided with a plurality o't apertures 2i in one or moregroups, as may be desired or found necessary, said disks being connectedtogether by the perforatedV cylindrical tubes 22 which, at theiropposite ends, are provided with a plurality ot lugs 23 turned over andsecured upon both surfaces et the disks, this means aiiording a readyand satisfactory way oivsecuring the heating or the cylinder 2 and3,-o't and 20, each radiating tubes to the disks 19 and 20. The

Yproviding thereby a very effective deiiector heating drum thus composedis suspended within the inclosing cylinder 1 by means of bent arms orbrackets 2a secured by vertical intermediate portions to the upper endot the cylinder 1 by means of screws 25 and nuts 26. The arms, at theirlower ends, are each bent inwardly to provide a horizontal support 27 onwhich the disk 19 is set and to which said disk is secured by means ofscrews 28 and nuts 29.' Thus, with a plurality of supporting` bracketsor arms, such as 24, the drum is rigidly mounted within the cylinder 1,clear of the walls thereo't, a spacebeing provided between the disks 19and 2O and the cylinder 1 for the passage ot heat from the chamber 30between the burner` 3 and the disk 20, in which chamber the burner 3 islocated. Between the heating tubes 22 and the wall otthe cylinderanother chamber is provided, and between the upper disk 19 and theheating tubes and the'upper end of the apparatus still another chamberis provided, as presently described. The brackets or arms 24 areoutwardly bent so as to extend a considerable distance beyond thecylinder l and then are inturned, as at 31, to provide a ll-shapediiange or support for the flanged open end 32 of the conical dome 3S ofthe apparatus. Bracket arms 24 rigidly support the dome 33 in positiondirectly above the cylinder 1 and separated from the latter by a.sur'licient space to allow of the escape of the heat into thesurrounding atmosphere. Preferably, the dome 33, at its lower end, isconsiderably greater in diameter than the cylinder l,

for the heat and enabling the said dome to thereby carry the heatoutwardly a considerable distance from the cylinder 1 into thesurrounding atmosphere. The dome 33 thus provides an extensive chamberabove the disk 19 and the heating drum; and said dome is provided with aplurality ot apertures 3a suitably arranged for the escape olf heat fromwithin the said chamber directly into the surrounding atmosphere. .\tits upper end, the dome is provided with a ccntral aperture surroundedby a short inturned 'tiange 35, upon which rests a tei-rule or sleevesurrounding a screw boli" 3T, which extends through the aperture in thedome 33 and is securely held b v :l nul ils on the threaded end oit thebolt. cap plate 3S) conical in Vtorni is mounted upon the terrule 3G andhas the stem ot the bolt 3T passing theretlnrough. Thus. the head of thebolt tightly ecures the cup plate 2in upon the :terrule 3G and the.support oi' the said cap plate upon the dome 33 is unite rigid. TheYfunction oi the cap plate is to prevent the heat rising from the dome.or any products of combustion passing through the dome. reaching theceiling. Thus the possibility oit blackcningor soiling the ceiling' iseliminated. The cup also bas the function of deflccting the heutrit-:ing through the dome downwardly and outwardly into the surrounding`atmosphere.

The heating apparatus produced as thus described may be, as shown inlig. l, mounted upon the iixture 1li, which is the usual gas bracketarm, after removing the lighting tip therefrom. Il? it is desired toobtain light and heat simultaneously. the entire burner and tip can beremoved from the valve member 13 oit the bracket arm and in its place afixture can be applied as shown in Figs. and G, the fixture in thisinstanci` being a T-shaped member 40, the stem ol' which is applied tothe valve member lil oi the bracket arm 14.-, and the head ot which hasextending therefrom in opposite directions the pipes or arms Lll and112, the arm L11 having my heating ap] nuatus applied thereto, as shownin Fig. 4. and the arm A,li having the usual gas cock and burnerindicated generally by 4163 applied thereto. Thus, heat and light can befurnished at the same' time through a single fixture ,il having appliedthereto the attachment l0-42; and heat or light may be obtained asdesired. Instead oit supporting my heating apparatus upon a fixed arm orbracket such as la, it may be applied to n heavy portable base L14, asshown in Fig. G, the same consisting oi a weighted or very heavycircular or other shaped member adapted to rest on a table, the floor orotherwise, and having extended centrally therefrom a stem 45 connectedwith a fixed pipe 1G. in turn coupled in suitable manner to a flexiblepipe 47 secured to the source of supply.

The stem 45 of the base or support t1 has the heatingand lighting ixtureshown in Fig. 5 applied thereto in the same manner as it is applied tethe bracket arm 14. Thus a lighting and heating device portable incharacter can be set upon a table, in a room or otherwise; to provideeither or both heat and light in manner similar to a drop light,students lamp, etc.

From the foregoing it will be seen that I have' produced a very simpleand effective heating apparatus which is adaptable to the ordinary gasjet or bracket arm as a substitute for the light burner, or Which can beso applied to a supporting member or device as to afford both light andheat simultaneously. It Will also be seen that my heating device willsupply a very great amount of Warmth, and, when it is thoroughly heated,Will radiate heat quite extensively into the surroundingatmosphere andafford a sufficient heating medium even in very cold Weather.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

l. A gas jet heater comprising a cylindrical body; a heating drum andmeans for suspending the same Within the body; means at the bottom oithe heater for supporting the 'same upon a gas fixture; a dome mountedupon the body; and a cap mounted centrally upon the dome with itscircumference free to prevent products oi' combustion from rising.

2. A gas jet heater comprising a body portion; a perforated baseentirely closing the body portion; a burner mounted centra-lly in thebase and having an extended stem for supporting the heater upon a gasfixture; a drum consisting of a plurality ot' perforated tubes joined atopposite ends by disks; and means for suspending said drum within thebody portion out of contact with the latterand above the burner.

3. In combination With a support through which a supply of gas may beobtained; a h'xture applied thereto; a source of light secured to oneend of the fixture; and a source of heat secured to the other end oi?the ixture; said source of heat comprising a supporting base; a'cylindrical heat radiating body; a heating drum Within said body; a domemounted on said body; and a cap mounted upon the dome.
